A Federal agency last month upheld allegations that black, Latino and female police officers in Suffolk County, N.Y., were subject to repeated discrimination on the job and were routinely denied promotions.

The U.S. Equal Opportunity Employment Commission, acting on bias complaints brought by 32 minority officers, issued its administrative findings on Dec. 13. The commission found “a pattern of discrimination against blacks, Hispanics and females,” and added that the suburban police agency had failed to comply with a 1986 Justice Department consent decree to hire more women and minority officers.

About 90 percent of the agency’s 2,710 officers, who are among the highest-paid cops in the nation, are white males, according to the EEOC.
